Location-plate, it is connected with objective table by many support bars, and described location-plate is provided with a plurality of screws, and described support bar passes screw and is fixedly connected with location-plate by locking nut;
Hold down gag, it comprises thrust plate, pressure strip, helical Bourdon tube and many depression bars, and the bottom of described helical Bourdon tube is fixed on the pressure strip, and apical support thrust plate; One end of described depression bar is fixed on the thrust plate, and the other end is mobilizable to be passed the screw of location-plate and fix by locking nut.Promote depression bar during use, it is downward that depression bar drives thrust plate, and helical Bourdon tube is subject to thrust plate and promotes rear supercharging, pressure strip is pushed to objective table, at last lock nut is tightened, thereby pressure strip is pressed on the objective table, after press filtration is complete, unclamps locking nut and helical Bourdon tube is retreated unclamp;
Filter, it is a projective structure that is arranged at described pressure strip bottom surface, comprise filter frame and be installed in the interior filter plate of filter frame, the shape size of described filter frame and filter chamber cooperatively interacts, when pressure strip was pressed on the objective table, filter frame and filter plate were pressed into simultaneously in the filter chamber slurry in the filter cloth bag are carried out press filtration;
Water outlet is chewed, it comprises the perforate that is arranged on filter frame, the pressure strip, and the perforate consistency from top to bottom of the perforate of filter frame and pressure strip, after slurry is pressed, the solid constituent of the material in the filter cloth bag is owing to the aperture of its particle diameter greater than filter medium (filter cloth) is trapped within the filter chamber, solid constituent forms filter residue in filter cloth bag, filtrate is then chewed discharge through the water outlet on filter frame and the pressure strip.
Further, be provided be used to the gasket seal that prevents that slurries from overflowing between described filter frame and the filter plate.
Further, the body of rod of described support bar and depression bar is equipped with screw thread, and locking nut is by the screw-threaded coupling on the mesh rod.
Further, described objective table both sides are provided with for the leveling bolt of regulating the testboard levelness, and this equipment can be put on platform reposefully.
Further, for keeping thrust plate and pressure strip steady, have at least a support bar to be arranged in described thrust plate and pressure strip plays the firm support effect.
The invention has the beneficial effects as follows: the present invention is a kind of press filtration testboard that is applicable to the low dose of press filtration test in laboratory, adopt the pressure under the helical Bourdon tube supercharging simulation working condition, adopt high-power infusion to enter material realization supercharging with working condition and compare, the present invention adopts the helical Bourdon tube supercharging simpler and low-cost.In addition, filter cloth bag used in the present invention can take out easily, and this is so that change the more convenient to operate of filter cloth bag or material under the laboratory condition.The present invention is simple to operate, failure rate is low, and the condition of production of the large-scale press filtration of energy simple analog is for being a kind of manual simplified pressure filter experiment equipment that is suitable in the laboratory popularization.
